| Turbo Direct Pipe
Does anyone make a Turbo Direct Pipe for the LB7? I am looking to upgrade my system and it doesn't make sense to me to add a 4 inch exhaust to 3 inch pipe. I crawled under the truck and see where the pipe actually funnels down before it attaches to the 3 1/2 inch pipe. |

| did your 4.5" pipe connect directly to the turbo or up under the truck? The actual downpipe runs against the firewall to the turbo. Most likely the pipe you have connects to the actual downpipe. Check out the link I posted above...it has pictures of the actual downpipe...it can be a PIA to change.
